Class: Grade 8, General Science Unit: Volcanoes Topic: Volcanoes Change the Landscape
Instructional Objectives:
Model the movement of molten rock through fractures in the lithosphere, over Earth's surface, and under water.
Devise working definitions for the words magma and lava.
Identify landforms created by molten rock.
Introduction:
Now that we have learned the properties of molten rock and how its viscosity predicts volcanic eruption and composition, we will learn the different landforms which can be created from it. I will explain that by learning this, we can predict what a location could look like in the future or study how a location formed in the past.
I will say, “Today you will be working together to model the movement of molten rock to create different types of landforms found both on land and under water. By the end of this class you will all be able to identify different landforms created by molten rock.”
Before we begin today's lesson I would like to review what we learned yesterday because viscosity has a lot to do with how various landforms look and form. We will then discuss some features from around the world and make some hypotheses about how we think they formed. From here we will perform experiments that will prove our hypotheses right or wrong. Some of the features we can discuss are the Mid Atlantic Ridge, lava domes at Valle Calderas, lava tubes at Shiprock, etc. While discussing these landforms, I can show the classes photos online.
Activities & Assignments:
5 minutes: Review what we learned in previous lesson about volcanoes.
30 minutes: Experiment 1 - Investigating magma and new landforms - Students simulate the movement of magma, using "model magma," as it rises through fractures and changes the shape of the land on the surface. Students come up with a working definition of magma.
15 minutes: Review what we learned from the magma and new landforms experiment. View pictures of different landforms created this way.
30 minutes: Experiment 2 - Investigating lava and new landforms - students use melted wax to investigate how cooling lava forms new land both in and out of water. Students come up with a working definition of lava.
15 minutes: Review what we learned from the lava and new landforms experiment. View pictures of different landforms created this way.
2 minutes: Extra clean up time.
